appreciate
əˈpriːʃɪeɪt,-sɪ-/

recognize the full worth of.
"she feels that he does not appreciate her"
understand (a situation) fully; grasp the full implications of.
"they failed to appreciate the pressure he was under"
It's just lame that people have given this guy a pass, when others in the same situation and same problems (Mike Tyson) didn't get a pass. Watching all this polite "looking the other way" and celebrating a rapist just seems... unsavory.
